Lol.... the 3rd ear plug has caused a few chuckles Altho the number of folk wh seem to loose just one is silly (ive done before now). The aluminium cases have a very small stash compartment in the bottom to hold the spare plug , or owt else ya might wanna stash away

Vinne... I never claimed they are perfect, that would be silly, lol... read again... but for £12.99 they really ARE amazingly goood... better than £70 earplugs i have used in the past & not £100+ like many custom made earplugs
